+
+A 40% custom keyboard designed and produced by [LazyDesigners](http://lazydesigners.cn).
+
+Keyboard Maintainer: [Erovia](https://github.com/Erovia)  
+Hardware Supported: Dimple  
+Hardware Availability: Check for GBs on [Geekhack](https://geekhack.org) and on [LazyDesigner's homepage.](http://lazydesigners.cn)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make lazydesigners/dimple:default:dfu
+
+To enter the bootloader, either short the pins on the PCB or the RESET button on the FN layer.
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
